WHAT IT DOES

What list-contacts does on MCP Google Workspace

AI agents call list-contacts to retrieve information from MCP Google Workspace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list-contacts is rated Low

While contacts may contain sensitive PII (names, emails, phone numbers), the tool itself performs only read access, making it a Read category risk.

From the tool's definition Tool name 'list-contacts' and description states it 'List[s] Google Contacts' and 'Returns: array with resourceName, names, emailAddresses, phoneNumbers per contact.' The use cases are 'viewing contact list, searching by name,' which are retrieval operations…
